Number of attackers at Kenya Mall may have been fewer

According to a top Kenya government official, four attackers can be seen on television footage during the terrorist attack on Westgate Mall in Kenya, which killed at least 67 people; this is an indication that the number of attackers could be fewer than previously believed.

The government had initially said there were 10-15 attackers at the mall and terror group al-Shabab claimed responsibility for the attack there. The group has also threatened more attacks in the region for sending troops to Somalia.

The official spoke anonymously for he's not supposed to reveal information about the investigation.
